Although many contemporary reviews refer to the film as Damn Citizen!, the screen credits do not include the exclamation point. The opening credits begin with the following written statement: "What would you do if you had a chance to fight crime in your community-personally? For the next 90 minutes you will see the story of one man who was asked to do just that-a citizen no different than you. This motion picture was filmed entirely in the actual location in which it happened." The opening and closing cast credits vary slightly.
As depicted in the film, Col. Francis C. Grevemberg was a World War II hero who, as superintendent of the Louisiana state police, cleaned up much of the graft and corruption in the state. When Earl Long became governor in 1956, however, he overturned many of Grevemberg's accomplishments, stating that the State Police should not "harass and intimidate the citizens."
According to a May 24, 1957 Hollywood Reporter news item, director of photography Ellis W. Carter became ill during production and was briefly replaced by Fred Jackman. Although Hollywood Reporter news items add Barney Grant and Wendall Clark to the cast, their appearance in the final film has not been confirmed.
